From what I have read over 23 is a good time for a female to have jaw surgery as generally growth as stopped.
I am over 30, second time in braces, just had SARPE surgery (narrow upper ) and still have expender on. I have recessed chin, 10mm overbite and require double jaw surgery this year.
I found a great maxfac surgeon (if you can get a great referral for a good one, it's worth just meeting for the exercise). He looked at my X-ray and explained what I needed, why and how. I think the consult sort of confirmed all the things that I thought were 'off' with my jaw/bite. When I spoke to him I knew he was the guy to do it for me.
I still have a few people say " why would you bother"? I bothered because I was looking long term, I want to be confident about myself and I want my natural teeth to see another 10 years in my mouth (as appose to a sparkling new set of dentures).
There is no obligation when you meet with a surgeon, even to investigate, walk away and think some more about it. You have far more great years to benefit, maybe just investigate it can't hurt...wish I had at your age, I procrastinated instead!
Good luck
